IMPLEMENT FOR SOWING sEEn.

Application filed May 25,

To all whom it may concern. H Be it known-that we, VVALTER DUNN, residing at 10, St. Margaret Street, Canterbury, in the county of Kent, England, and ARTHUR Horn CONSTABLE, residing at The Quarry, Penshurst, in the county aforesaid, both subjects of the King of Great Britain and Ireland, have invented a. new and use-. ful Improvement in Implements for Sowing Seeds, of which the following is a full and complete specification.

This invention relates to implements for sowing the seed of cereals and other agricultural produce and it has for its objects to form a smooth and even bed for the seed so as to ensure that all the seed is planted at a uniform depth. A further object of the invention is to effect the sowing so as to produce larger crops and to econmize in the use of seed and fertilizers. r

\Vith these and other objects in view the invention comprises the various novel features of construction, combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawing and pointed out in the claims hereto appended. I

Figures 1 and 2 are views in side and-end elevations showing the application of this invention. Figures 3, 4 and 5 are views in. side elevation, rear elevation and plan-on an enlarged scale-showing the improved hoe. Figure 6 is a view in perspective of the hoe shown in Figures 3, 4 and 5, and Figure 7 is a view in perspective of a modi fied form of said hoe.

On a frame 1 is mounted in suitable bearings a transverse axle 2 on the ends of which are mounted the traveling wheels which are each coupled to said axle by any suit-able form of one-way driving clutch. On the top of the frame 1 are mounted the seed and fertilizer hoppers 3 and 4 which are provided with rotary distributors which may be of any suitable type. In a suitable position in relation to the axle 2 and to the distributors is a countersha ft 7 which is geared to the axles 8 and 9 of the distributors by sprockets and chains or other suitable gearing. The countershaft 7 is driven from the axle 2 by sprocket and chain gearing the sprocket 10 of said gearing on the axle 2 a quadrant.

. slot 21* a hoe15 forforming a. furrow or for turn- 1 ingup a ridge according to thenianner in which the seed is to be sown, a hoe 16 for leveling and smoothing, the bottom of said furrow by filling in any inequalities left by the hoe 15, a spout 17 connected to the hopper-s 3 and 4 for distributing the seed and the fertiliZer,and.a hoe 18 for turning back the soil into the furrow to cover up the seed. For heavy land it so-lidate the seed bed formed by thehoe 16 to which end plate-20 may be arranged to follow said hoe and can conveniently be mounted on the bottom both of said hoe and of the adjacent seed spout as shown in Figure'7.' ounted in suitable bearings carried by the main frame 1 is a shaft 19 which-car ries a series of arms or leversQO which are connected to the bars 14 of the sub-frame 13 by adjustable links 21. On the shaft '19 is fixed a hand lever 22for the purpose of simultaneously raising and lowering the elements of said subfra-me, said lever being provided with adjustable locking means such as a trigger co-actingwith a fixed notched I The links 21 tached to the bars 14 by and a plurality of holes 14* in the bars 14 and are connected to the arms or levers 20 by springs connections which will allow the individual bars to rise independently of the others in case they should meet obstructions. A convenient construction is to connect the link to its arms or lever 20 by means of a and to mount a spring 33 on said link which operates between a collar 34 thereon and any suitable fixed abutment.

The hoppers 3 and 4 are each connected with the series of spouts 17 by means of shoots 24 and 25 which are so shaped and arranged that their spouts 17 in any position said spouts can assume.

The hoes 15 and 18 are so mounted on the bar 14 that they can be easily and readily mounted or disconnected and so that they can be located on either side of said bar and may be desirable to conare adjustably at; means of pins 23 ,a-xle bymeans of a lower ends lead into said at any height with respect thereto. The spout 17 is also so mounted that its position relative to the hoes in the vertical plane can be varied.
